Step‑by‑Step Instructions for Baked Salmon with Spinach and Mozzarella
Step 1: Sauté Aromatics
Heat 2 tablespoons of olive oil in a skillet over medium heat. Add the sliced onions and sauté for 3-4 minutes until they turn translucent and soft. Then, add minced garlic and cook for an additional 30 seconds until it becomes fragrant. This step sets the flavorful foundation for your Baked Salmon with Spinach and Mozzarella.
Step 2: Add Spinach
Incorporate the thawed and drained spinach into the skillet with the sautéed onions and garlic. Stir gently, cooking for about 2-3 minutes until the spinach is heated through and well combined with the aromatics. Season the mixture with salt and pepper to taste, and remove it from heat before mixing in sour cream for added creaminess.
Step 3: Prepare Salmon
Preheat your oven to 175°C (347°F). While the oven heats, season the salmon fillets generously with salt and pepper. In a separate pan, sear each side of the fillets over medium-high heat for approximately 2 minutes. This step helps to lock in moisture and enhances the flavor of your Baked Salmon with Spinach and Mozzarella.
Step 4: Assemble Dish
Grease a baking dish and place the seared salmon skin-side down into it. Evenly spread the creamy spinach mixture over each salmon fillet, ensuring every piece is well-covered. Top it off with a generous layer of mozzarella cheese, which will bubble and form a golden crust while baking.
Step 5: Bake
Carefully transfer the baking dish into the preheated oven. Bake for about 15-20 minutes or until the salmon is opaque and flakes easily, ensuring the internal temperature reaches 63°C (145°F). Keep an eye on the cheese; it should be melted and slightly golden at this stage for a delightful finish.
Step 6: Serve
Once baked to perfection, remove the salmon from the oven and let it rest for a few minutes. Plating is next—serve each fillet with a generous scoop of the creamy spinach topping. This Baked Salmon with Spinach and Mozzarella is now ready to delight everyone at your table.
